Final answer:
Alice is 5 km away from home, which equals 500,000 centimeters. None of the multiple-choice options provided are correct since they do not match the accurate conversion from kilometers to centimeters.
Step-by-step explanation:
Alice is 5 km away from home. To convert kilometers to centimeters, we use the conversion that 1 kilometer is equal to 100,000 centimeters (since 1 kilometer = 1,000 meters and 1 meter = 100 centimeters).
Therefore, to find out how many centimeters Alice is away from home:
- 5 km × 100,000 cm/km = 500,000 cm
So, Alice is 500,000 centimeters away from home. None of the options listed (a. 1200 cm, b. 500 cm, c. 50 cm, d. 5,000 cm) are correct.
